SPECIFICATION forming am of Letters .Patent No. 628,986, dated July 18, 1899. Application filed December 31, 1898- Serial No. 700,783. (No model.)

To a whom it may concern:

Beit known that I, HIRAM R. LAMB,,acitizen of the United States, residing at Adrian, in the county of Lenawee and State of Michigan, have invented a new and useful Die for Joining Intersecting Wires, of which the following is a specification. This invention relates to dies for interlocking the crossing wires of a wire. fabric intended, primarily, for fencing purposes, and it is designed inore particularly as an improvement upon the device for joining intersecting wires patented to George M. Lamb and Hiram R. Lamb by United States Letters Patent No. 472,059, dated April 5, 1892.

The object of thisinvention is to facilitate the application of the locking-wires to the in tersecting or crossing wires and to insure the firm union of the several wires at the joint, thereby saving time in the operation of joining the wires and effecting economy in the manufacture of the wire fabric by increasing the productive capacity and the speed of operation of the machine and turning out an increased quantity of fabric within a given period of time.

The improvement consists inv coacting dies having feed-slots for the staple-like fasteners, arranged diagonally across the lines of the wire-receiving channels, the latter being provided in the working faces of the dies to have the deep wire-channel of one die cross the correspondingchannel of the other die at right angles in order to properly positionthe wires in relation to each other and to the feed-slots for the staple-like fasteners and each die havin g semispiral grooves which entend in the general direction of the deep wire-receiving channel thereof, whereby the locking-fasteners maybe fed simultaneouslythrough the diagonal slots of both dies to be positioned therebyin oppositely-inclined directions across theand the semijoint between the crossed wires, spiral groove of one die operates on the (510s ing of the dies to twist the ends of the staplelike fastener fed by the other die around the wire which is contained in the saiddie that effects the twisting of the staple-fastener.

The invention further consists in the novel construction and arrangement of parts, which claimed.

will be hereinafter fully described and To enable others to understand the invention, it is' illustrated in the accompanying drawings, forming a part of this specification, and in which- I v,

The blocks of the coacting dies of the present invention are indicated by the numerals 10 and 11 in the drawings, and these dieblocks are mounted in a machine for movement toward and'from each other simultaneously, or substantially so. The machine is not represented in the drawings because it may be made rate application, the present application bein g for the improvement of the dies constructed in a novel manner for the purpose of feeding and twisting the two staple-1ike fastening'wires simultaneously around the crossed wires, near the joint thereof.

' he die-block lOhas acentraldiagonal feedslot 12 formed therein to extend entirely through said block, and the working face of the block is'provided with a deep wire-receivin g channel 13, which extends entirely across said working face at the middle portion of the block. The diagonal slot- 12 lies in a plane which intersects with opposite corners of the die-block, gle-across the wire-channel 13 to intersect the subject-matter of a sepa" and said slot lies at an an-' secting or crossing therewith at the center of the die-block. The working face of the die is furthermore provided with a shallow wire-channel 14, which extends at right angles to the deep channel 13, and said die is also provided with a semispiraltwisting-groove 15, which extends in the general direction of the deep wire-channel 13. This semispiral groove 15 has its sections or lengths disposed on opposite sides of the diagonal feed-slot 12, and the respective sections are inclined in opposite and parallel directions to each other for the purpose of twisting the respective ends of one staple-like fastener, which is fed by the other die 11 in opposite directions around the same length of one of the intersecting wires, said oppositely-twisted ends of the staple-like fastener being disposed on opposite sides of the interpoint of the two wires, as will hereinafter appear. Finally, the Working'face of the die-block 10 is provided with other die-block, said shallow recesses 15, which lie obliquely to the axis of the deep wire-channel 13 and are disposed on opposite sides of the semispiral groove 15 and the diagonal feed-slot-12. The.

other die-block 11 is constructed in an analogous manner, and it' is provided with a central diagonal feed-slot 16, thedeep wire-chann'el 17, which intersects with the diagonal feed-slot, the semispiral groove 18, arranged to extend in the general direction of the channel 17, so as to intersect therewith, and having its respective sections which lie on opposite sides of the feed-slot 16 inclined in reverse and parallel directions to each other, the shallow wire-channel 19, lying at right angles to the deep channel 17 and intersecting therewith and with the feed-slot, and the shallow inclined recesses 20. The die 11, however, is arranged to present its working face in a position for its channels, grooves, and recesses to lie in planes at right angles to the planes of the channels, grooves, and

recesses of the die-block 10, and proper registration of the two dies in relation to each other is insured by the provision of guidepins 21,-which are secured to one die-block and are adapted to lit in openings 22 in the pins and openings being disposed entirely out of the way of the depressions in the Working faces of the dies. These die-blocks are also provided with transverse screw-holes 23, adapted for the reception of screws,which are designed to be countersunk within the working faces of the dies and which serve to rigidly fasten the dies to the moving elements of the machine for operation therewith.

In the working or operative position of the two die-blocks the guide-pins direct one die in such relation to the other die that the deep channel 13 crosses the deep channel 17 at right angles, and this channel 17 of one block 19 of the first-named block.

coincides with the shallow channel 14 of the other block, while the deep channel 13 of the last-named block coincides with the channel The diagonal slots 12 16 of the two blocks lie at right an gl'es to each other, so that the feed-slots of the two blocks will present the staple-like fasteners in oppositelyinclined directions across the intersection or joint between the two wires which are contained within the deep channels 13 17 of the blocks. The semispiral grooves in the working faces of the blocks will lie at right angles to each other and in positions to receive the ends of the staple-like fasteners, which are fed in oppo site directions through the diagonal slots of the two blocks, and the shallow recesses of the die-block 10 will be presented opposite to certain portions of the semispiral groove 18 in the die-block 11, while the inclined re-' cesses 20 in said die-block l] are coincidentwith certain portions of the semispiral groove 15in the die-block 10. Assuming that the dies are in proper registration and the machine in which the dies eration, the wire fabric is advanced to present one wire 24 in the deep channel 13 of the die-block 10 and another wire 25 in the deep channel 17 of the other die 11. fasteners 26 26 are passed in opposite directions through the diagonal feed-slots 12 16 of the dies 10 11, respectively, so that the staple-fasteners will lie at right angles, to

each other and diagonally across the interends of the staple-fastener 26 of the die-block 11 are received within the ends of the semispiral groove-15 of the die-block 10, while the ends of the staple-fastener 26" in the dieblock 10 are received within the ends of the semispiral groove 18 of the die-block 11. The dies lock or hold the two crossed Wires in theirproper relative positions, and they guide or direct the staples to proper positions'diagonally across the intersection of the wires. The staples are forced into the grooved dies by a plunger or plungers, which enter the diagonal slots on an angle at the crossing-point of the intersecting wires, and these plungers carry the staples with them. The grooves 15 18 of the two die-blocks deflect or turn the wires 26 26 around the crossed wires 24 25, and each staple-like fastener has its ends twisted in opposite directions around its proper wire. The fastener-wire 26' has its ends 27 28 twisted around the Wire 2% on opposite sides of the crossing or intersecting point of the wires 24 25, while the other staple-like fastener 26 has its ends 29 3O'tw1sted in opposite directions around the wire 25 on opposite sides of the intersection of said wires 24 25.

From the foregoing description, taken in in opposite directions are mounted is in op- Staple-like Connection with the drawings, it will be seen that the dies are constructed for the simultaneous feeding and proper positioning of the two staple-like fasteners, which, after the dies are closed or brought together, are bent .or twisted around the crossed wires on opposite sides of the intersection thereof by means of plungers forced from opposite directions, thus providing at one operation for the secure union of the crossed wires by the two staple-like fasteners.

Changes may be made in the form of some of the parts while their essential features are retained and the spirit of the invention embodied. Hence it is not desired to limit the invention to the precise form of all the parts as shown, reserving the right to vary therefrom.
